ELECTRIC PROTECTION SYSTEM.

Application fi1ed May 21,

To all whom it may concern:

Be it known that I, JOHN P. VVILLIAMs, a citizen of the United States, and resident of New York, in county and State of New 5 York, have invented certain new and useful Improvements in Electric Protect-ion Systems, of which the following is a specification.

This invention relates to electric protection systems, and has special. relation to an improved static system of protection for efiecting, through operation of a high-tension spark coil or transformer, a stunning blow or shock upon a person attacking the system.

Heretofore it has been generally customary, in connection with electric protection for hanks,jewelers, ,and analogous services, to depend upon the sounding of an alarm 20 or a signal suitably located to notify the desired authorities of an attack upon the system. Such alarm systems, as now usually employed, are not operative to shock or stun a burglar or attacking person, and the alarm signals not only frequently operate falsely through defective conditions but their operation may be defeated by cutting of wires and other methods of burglarous attack without liability to personal injury from the circuits oi the system.

While my improved static system of ele tric protection may be employed in connection with all systems employing alarm signals, as a su plementary protective feature, the improved system is operative to eliminate dependence upon an alarm signal in to give a stunning blow or shock by electrical force to a burglar or attacking ture;

In carrying out the operative purpose ust stated, the conditions of the improved system are such that when the attacking person places his hands in contact with the protected structure, or otherwise contacts with the conducting structure, he makes contact in a circuit through the secondary of a hightension electrlc spark coil which is so wound that an extremely high Volta e (to a max'u mum of many thousands of v0 ts, as desired) can be secured at the secondary through in duction from theprima coi ,thu's produc inc a' very mm slice the strength of person the instant his hands are 40 placed in contact with the protected struc- 1921. Serial No. 471,444.

which can be made as great as required under the desired conditions and sufficient to stun the attacking person into insensibility.

The usual alarm signal be employed in the system, if desired, to operate simultaneously with the short circuiting of the secondary coil of the hightension shock element.

My improved system is adapted to a wide range of application and use, for protection of bank vaults, safes, bank counter grillework. prison cells, and in fact any service where electric protection of a structure or apparatus or device is desired, such as entrances to office buildings or private houses, the protection of automobiles against thievery, etc., and the improved static system can also be app-lied as a su plement to protective electric systems of t e alarm signal type which are already installed and in service.

In the drawings, I have illustrated diagrammatically *he wiring of the improved system, and its primary control apparatus, in its relation to several of the various con ditions of service connection for which it is adapted.

Referring to the drawings, X designates a high-tension spark coil, which is made up of a primary and a secondary coil, 79 and s, wound around an iron'core, A A source of electrical energy, as a battery, designated at B, is in connection with the primary coil of the sparker through an interrupter, Y, embodying an armature. D, mounted on a spring contact, d, operative with relation to an adjustable contact, /q and in conjunction with the contacts (I and y there is employed a condenser, as at Z, for governing the amount of the spark through the interrupter. The primary is usually wound with a few layers of cotton-insulated wire wound over the core and preferably of No. 18 B. and S. gauge, and the secondary consists of several thousand turns of properly insulated wire wound over theprimarv. In operation, every time the interrupter shuts bit the battery current in the primary there are currents induced in the secondary which cause sufficiently high voltage to span or 'ump across a space, and if contact is made y a person a shock of desired intensity is given; and when the current is sent througp the prima with the interrupter properly ad dated as to contact; the mter auxiliary can also is connected to an rup-ter instantly commences a spark will jump between wires.

In one operative service under the conditions of my improved static system there is mounted within a protected va t the spark coil X, the battery B, an electric clock (of any usual construction) C, and all the wiring in connect-ion with the primary coil of the sparker. A relay, as at E, for causing actuation of a continuous signal or alarm may also be mounted in circuit. The wiring in connection with the secondary coil of the sparker is connected to binding posts, *-G, which arealso inside the yault The to operate and the secondary coil .9 of the sparl: plug. extend wires. f-

the vault or suitably located, as J). ne side of the secondary coil is thus grounded through a part of the protected structure which by an attacking person, and the other side insulated part of the protected structure which must be stood upon or contacted with by the attacking person.

An auxiliary hell or signal attachment may, if desired. be interposed in the circuit of the wires f-g, by a relay, as shown at H. constituting controlling means and wired in series with one side of the secondary coil s by connection with the wire y, the relay aving its contacts. 32-33. normally open, so that if the secondary wires are short circuited a current is sent through the relay and attracts its armature. 34, against its core, 35. thereby closing contacts and actuating the alarm bell or signal, 31, in the circuit through connecting wires 37 and 38, and a battery. 36. S signal circuit can cuit connection with the have also md1cated, 1n the diagrammatie illustration, an auxiliary circuit conmust be touched nection with the insulated wires, L, which are usually contained in a metal line conduit or cable casing. as at M. in burglar alarm systems as now generally employed, it being understood that in such alarm or signal sys tems the wires L, and also the conduit casing M if desired. are included in the general protective circuits which tected structure and actuate an alarm, and are employed for carrying the wires thereof to an outside alarm or signal station. In this connection, the wire of the secondary circuit f-g is connected a wire, 2;, with the cable wires L. and the metallic conduit M is grounded through a wire, m, to the grounded wire f of the other side of said secondary circuit, and thus an attack upon the cable and conduit by cutting or otherwise causing closing of the secondary circuit will cause the desired shock action. 85 I have also illustrated a circuit conneef tion with the metallic grille-work of a bank or protected structure, in which the grillework, as at lV. is grounded by connection. as y a wire, in. with the grounded side f of the secoidary circuit fg, and an insulated floor plate J or part which must he stood upon or contacted with by an attacking person is connected, as by a wire, m, with the other side g of said secondary'circuit. It will be understood thatthe side f of the secondary circuit is grounded through any suitable or adapted metallic part of the structure to be pro tected, as variously indicated at N in the grounded in series with a switch, as at S, across,

contact posts, as at 1-3, or with the clock cut out and through a direct circuit across contact posts, as at 3-2, controlled by the switch S. y In operation with the clock C. the circuit is established from the positive side ofgthe battery B through a wire, 39, to a contact post, 0, in connection with one end of the primary coil 7), through said primary coil and through the interrupter Y to a binding post. P. and through a wire, R, leading to an insulated key-switch, T

switch side of the vault or protected structure,

reserve purposes), through said switch and frame of the clock C and 7 contacts and hand, it, and

a wire, 40, to the contact post 1 of the switch S, across the switch to the contact post 3,-

and through a wire, 2: to the negative side of the battery B. The foregoing arrangement of wires or conductors and mechanism will cause operation of the spark coil X,

oessto the vault or producing the. desired hi h voltage in the secondary s, and establish mg the system in status for'operation, to shock or stun an attacking person, across the grounded side of the secondary circuit f-g and theinsuated parts of the protected structure'which are in connection with the other side g.

The employment of the clock-control C is for the purpose of enabling the throwing of throw the system on automatically a night at a. predetermined hour and of at a predetermined hour in the morning, when acprotected structure was desired.

The insulated key switch T-is employed,

in serieswith the clock circuit, so that in the incircuit, between the positiveside interposed in the lamp circuit for event that the clock circuit should fail to throw the system oil an authorized personcan by opening the switch release the spark 1 coil from operation. For this purpose, said switch is preferably located in a secret or protected place external of; vault or protected structure. V

A signal lamp, W, may also be interposed o batte B and the oontrol-clockC and under conditions that when the electric current is ass through the clockcontrol a circuit 511011 the lamp willtbe completed through a wire, 4, connected with the wire 89 from battery B, throu h a fuse, 5,-in said conductor 4, through the amp, and: through a wire, 6, connected with the wire R wh ch leads to the clock-control. Thus, thcsignal lamp W will beo rati when currentis passing through t e cloc -control, llldlcflt ing that thesystem is on. Said. lamp signa'l is suitably-located at apoint external of the protected structure, and the fuse sis e purpose of precluding an'attack thereon by sending an outside current through the lamp and causing interference with the rotective system or burning out of the spar coil.

Inpractica'l operation, with the system under the conditions of an auxiliary gua circuit as above described, when the clockcon'trol C throws the system 05", (for instance, in the morning under bank, customs) the authorized operator can then enter the vault or protected. structure,;and the switch- "8 is-set across its contact posts 2-43. This cuts out the clock-control circuit and throws the control of the primary coil; thro h battery B for operation indepc'n out o the control-clock mechanism. The

i system is then operative as, for instance a" daylight protection in bank installation in connection with the grille work W which is in the secondary circuit f-'-g,. be

Auxiliary tmsuch grille-work} protection, there are employed separatehand contactssuita 1 located, back ofthe grille and operatabley the official" at the grille, Such contacts are in normally open position,

'as indicated at 7,-s, with a was, 'lfl extend "or a'foot ing from contact 7 to a wire, 4 8,10 Miamitive side of the battery B, and a wire; 11',

extending from contact 8 tothe-wire ,uto the negative sideof the battery. Under the operative conditions of the strut; ml 1 mangement'just describerhif an attac Essen stands u on the insulated. plate J in at of the 'gn la and touches'his hand to thsg'rounded parts of the grille, the operator by simply closing the contacts 7-8, estahlis as a. circuit from the positwe side of battery B thro h wire 39, the primary coil, and the some 'on to wire 10,-'- across the contacts, and through wire llback to the negative side of the battery "thus closing the circuit uthrough the p'riniary p of the spark coil and; causing, the system to operate to give a shock across the: plate J and gill-ills W. In the conditions as just set forth, I; a system will beoperative only so long as the o orator retains the normally-open contacts -,8 closed.

If, however, it is desired, byclosing contacts 7-8 or other suitably located similar normally-open contacts, as indicated at 12-13, to ofiectcontinuous service of the b more instant closing of said con-' tacts wit out retaining them closed, a circult arrangement is providedas follows; from the positive side of battery B through wire 9 and through a wire, 14,-acro s'jsthe contacts as at- 12-13, and through a wire, 15, to the coiluof the relay E, and contact 5 ring 47, armature plate 18, through the rams, 16 of the relay, 17, extending therefrom to the switch-contact 2, across the switch contacts 2-3, and back, to the negative side of the battery throu h wire 11. This magneti-zss the relay E an releases its armature plate, 18, which closes the circuit across normally-open conrdtacfs, as at 19-20, and the current islthen directed in continuous service through the primary coil p of the spark coil as lollows: from the positive side of'hattery B'through wire 891:0 one side of the primary coil, and

As an ad unct' 1n the operation of the relay E. an auxiliarv ball or signal may he "wires 9 end 14 to thrown into" continuous service when the uruguture of the relay is released, said signal, as 22, be' then in circuit as follows: from the positive side oflbat'tery B through a. Wire, 23, and a. wire, 24, to one side of the 51' al, and from the other sidocthereof tluou' r a. wire, -25, to contact 19, through relay-armature 18 and frame 16, and wire 17, across switch-contacts 2-3, and buck to the negative side of the battery tln'ough wire'vh- Control switches, operutable by hand or key, may be variously interposed-m the line wires of the system, as for instance in the circuit of wires 10-11, as indicated at 44, u'nd a line extension to an suitable or desired point may be currie by wires, us .at +46, indicated a's respectively connected to the system wires 1524.

It will also be understood that my improved static system may be employed upon either a direct or altcrnoting current and any source of electricul energy, whether a battery or other generi'tfio r.
